| Onyx uses a manned, floating, diesel powered, horizontal auger dredge platform fitted with a 6 or 8 submersible hydraulic pump. The horizontal dredge transverses across the pond along a cable anchored to each pond bank. Cable guides on the front and rear of the dredge prevent it from veering off course while a variable speed motor (reversible and hydraulically powered) pushes the horizontal auger into the sludge. |
|
| The dredge operator maintains constant communication via two-way radio with a shore-based operator (Shoreman) located at the dredge spoils area or sludge collection point. The Shoreman functions as a safety watch for the dredge operator and monitors the dredge line and discharge location(s). |
|
| NOTES: |
|
|
 |
Onyxs dredge will remove only slurriable/pumpable sludge from within six (6) inches of the pond bottom. Some applications may require washing or manually removing residual sludge left on the pond surfaces after the dredging process. |
|
|
|
The dredge is equipped with a fifteen-foot (15) boom (about 5 meters). In the event the pit/pond is deeper than 15 feet; Onyx normally works with the client to lower the pond/lagoon water level. |
|
|
|
The dredge enables the client to keep the pond/lagoon in service. On some applications, Onyx will use turbidity curtains at or near the pond outfall to ensure the dredging operations do not cause the discharge of suspended solids. |
|
|
|
It is important to work with the client to identify any submerged obstructions and/or structures to prevent damage to the dredge equipment and/or the submerged structures. |
|
|
|
Special attention must be paid to the pH and texture/abrasiveness of the sludge being dredged. Operation in corrosive and/or abrasive environments will cause significant equipment erosion and damage. |
|
|
|
The distance and elevation that the sludge must be pumped, and the density of the sludge must be evaluated on a project specific basis. In some cases, the use of a booster pump may be required to transfer sludge/spoils to the desired location. |
